  • the presence and the durability of the ionizeable finish may be determined by several methods. Where the ionizeable finish uses a sulfur compound such as a sulfate, an elemental analysis of the amount of sulfur present may be used. A rapid method is to perform a dyeing with a cationic dye such as methylene blue. In this case the cationic dye is attracted to the anionic sulfate group.
